Loading Outlook

There is evidence of an active Outlook web/Exchange Online service incident on November 12–13, 2026, so check Microsoft’s service status before making further changes to your computer.^1^

What to do now

1. Open Microsoft’s Service Health Status page, which is the official status path for Outlook.com access problems.^2^
2. Try opening Outlook directly at https://outlook.live.com/mail/.
3. Test Outlook on a phone or another device:
   • It fails there too: This strongly points to the current service incident or an account-side problem. Wait for Microsoft’s status page to report recovery.
   • It works there: The problem is probably limited to the browser or computer. Continue below.

If Outlook works on another device

Since restarting and clearing the cache did not help, test a different browser session:

1. Open an InPrivate/Incognito window and sign in to Outlook.
2. If it loads, temporarily disable browser extensions—especially AdBlock, Ublock, pop-up blockers, or privacy extensions—and reload Outlook. Microsoft documents that these extensions can prevent Outlook.com email from loading or cause timeouts.^3^
3. If necessary, test the latest version of a different supported browser:
   • Windows: Edge, Chrome, or Firefox
   • macOS: Edge, Chrome, Firefox, or Safari 16 or later

If Outlook remains unavailable only on this computer after those tests, use Outlook.com’s Help menu and select Still need help? → Yes. If you cannot sign in at all, use the sign-in support option described on Microsoft’s Outlook.com troubleshooting page.^4^

When contacting support, include the exact on-screen error message and any error code, but do not post account details or other personal information publicly.
